How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.

The Simba mattress is a hybrid model that combines conical mini pocket springs with multiple layers of foam, while the Emma Original is largely a memory foam mattress.
Interestingly, Simba used to be a pocket sprung memory foam mattress. 🤔
This previous version featured a layer of memory foam and a layer of latex foam, making it more similar to the Emma Original.
Simba Sleep has replaced the older version of the Simba mattress with one that's more breathable. 💨
The mattresses are now suitable for different people.
